Title:
network_data from metadata agent does not contain local routes for
adjacent subnets
Status in OpenStack Compute (nova):
Opinion
Bug description:
Description
-----------
The network_data.json provided by the config drive/metadata service is
missing local routes for adjacent subnets.
When using DHCP, these routes *are* provided via neutron's DHCP agent
correctly.
Steps to Reproduce
------------------
* Create a new network in Neutron with 2 subnets: 192.168.0.0/24 and
192.168.1.0/24 with gateways 192.168.0.1 and 192.168.1.1 respectively.
* Launch a new instance with an address in subnet 192.168.0.0/24 .
* Inspect the available metadata in `openstack/latest/network_data.json`
Expected Behaviour
------------------
There should be two routes specified in `network_data.json`:
* network: 0.0.0.0, netmask: 0.0.0.0, gateway: 192.168.0.1
* network: 192.168.1.0, netmask: 255.255.255.0, gateway: 0.0.0.0
Actual Behaviour
----------------
There is only one route specified in `network_data.json`:
* network: 0.0.0.0, netmask: 0.0.0.0, gateway: 192.168.0.1
Environment
-----------
* Ubuntu 14.04
* stable/newton - latest release from Git

For reference to Neutron's behaviour, see: [neutron.agent.linux.dhcp]
NOTE: this is also not properly implemented in cloud-init's static
networking implementation and an issue is currently open
HERE:[https://bugs.launchpad.net/cloud-init/+bug/1663049]. This may be
relevant for anybody attempting to test the behaviour.
